Average prices at the pump in the state are continuing to fall more than a dime per gallon of gas over the last week.

Aldo Vasquez with AAA Arizona said the average cost in the state is $4.75 per gallon.

“You’re going to find the highest averages in Graham County. They’re seeing averages at about $4.97. You’ll find the lowest averages in Pima County for $4.54," Vasquez said. 

Vasquez also said global economic concerns are pushing oil prices lower as the cost of west Texas Intermediate crude is now under $100 per barrel.  

But the average price per gallon in Arizona is still up $1.62 since last year at this time.
